The targa will be your only obstacle to overcome. That, and any issues that may arise from a repaint- depends on how extensive the repaint work was. I assume from concours successes that this is probably not an issue.

Calm down fellas. JuanPablo, he's just asking for opinions as to value, not trying to sell at this point, in this thread.

But we have pointed out to you that there is a strikingly similar car for sale currently. To get some opinions as to the value of your car, please consider posting some pictures. Larry's car has some unbelievably nice features that probably warrant his ask. Swang, you haven't provided much information, and people around here are tough customers when cars are represented as being in "perfect condition" and "concours quality" without more than just those words.

So, do tell us more about your car, and its "many other perfect components." Post some pictures, and I expect you'll get some valid and well thought out opinions here.

Color code doesn't sound like Viper to me. I believe the correct code for Viper is #225. I had a car with that code and the remaining areas of paint looked close -- but maybe a bit closer to Conda than the Viper repaints that are common today.

Techweenie is correct. Viper green code for 72-73 models is #225. There isn't even a paint code listed as 3810? Perhaps you could post a foto of the color code plaque from the driver door jamb.
Is your paint code a factory code or a code given to you by a poaint manufacturer?
Perhaps a silly question, but are you sure that your car is a 73? All paint codes for the 72-73 model years had 3 digits - not 4 as you state that your car has.

Maybe he is really just interested in buying Larry's 73E targa and doesn't know what fair market value is for it. By pretending he has a similar car, he didn't want to give anyone here the heads up on Larry's car.
On the other hand maybe he really does have a car to sell. With the way EBay seems to be bidding up cars these past few months, he may be better off just listing the car with a reasonable reserve price as discussed here and simply let the market bid it up from there. Not a bad idea really.
